A new series-parallel model for electrical conductivity of saturated clays that considers particles structure orientation
is presented in this study. The new model introduces a simple approach to consider the effect of surface
conductivity of clay particles on the electrical conductivity of saturated clays.

The proposed approach considers the clay particle and its surrounding diffuse double layer, as a single unit called an effective clay particle, and
assigns it an isotropic apparent electrical conductivity that can be determined using a simple experimental
method.
Therefore, the saturated clay can be considered as a two-phase material (binary mixture) namely, free
pore water and effective clay particles. Considering the clay particles structure orientation, the proposed electrical
conductivity model in this study geometrically configures the components of two-phase saturated clays in a
series-parallel form to determine the electrical conductivity of clay.

The proposed electrical conductivity model uses one parameter that can be determined experimentally and it reflects the anisotropic condition of the clay
fabric.
The validity of the proposed model is verified by comparing its results with the experimental results of
three different clay types reconstituted at different dry density levels and particles structure orientations.

The comparison shows the accuracy of the proposed model in predicting the electrical conductivity of saturated
clays
